Microsoft JPEG Hoax!

poorly written and poorly documented software we see today.

C was fantastic when it arrived. It made it possible to write
operating systems in another language than assembler. That
was a giant step forward. UNIX is based on it.

C++ is (IMHO) the worst thing that ever have happened to
programming. It is a totally horrible thingie. Too big, too
unsecure to be called really Object Oriented, not really all
that compatible with C, no standard for load objects, etc, etc,
etc ...

Hmmm ... Object Pascal ... As far as I understand Delphi Object
Pascal is a subset of Object Pascal. Don't like the sound of that.
I want to be able to write programs that runs on any platform.

Now - one of the most important issues is libraries. You need a good
set of libraries. Another one is support - you don't want to use a
language that don't support the latest things and where compiler
bugs is no longer fixed.

Now - I don't suppose any other language than C++ really supports
the latest direct x and have libraries for XML soap. Hmmm .. Java
might, but that is a toy language IMHO. It does not even have unsigned
integer. Lots of serious programming assumes that.

This is the error I'm getting:
"Unhandled exception at 0x7d706fa8 in iexplore.exe: 0xC0000005: Access
violation writing location 0x00000000."
So, I'm not just suggesting it. It is in fact what happens on my
computer.

That is exactly what I get also.

But ... sorry Carsten ... a buffer overrun might overwrite
the memory with zeroes and then use one of the zeroes as
an address. Then you would also get zero pinter exception.
So ... Guido might be right.

I'm asking you to back up your claim that this is a buffer overrun
problem that can be exploited.


It might be the same problem - or it might not be.
Anyone but Microsoft can only guess. That it is the
same (faulty) JPEG that crashes both codes hints at
it being the same.

If the buffer resides on the C-stack you have a potential
buffer overrun problem that can be exploited. Guido would
know where the buffer resides in his code.

Agreed that libraries are important - but with DLLs it's merely a matter
of translating the header from C to Delphi or VisualBasic or whatever -
using libraries can make your program independant of the language in which
the library is written. Direct-X from Delphi - no problem.

The latest move on libraries is .NET - and .NET programs can be written in
many languages. Even better: .NET libraries are available on Linux as
well as Windows. One has the chance to move on from the languages of the
past!

I just tried opening the test jpg and received the following
message:
"Internet Explorer has encountered a problem and needs to close. We
are sorry for the inconvenience."

Only the message ... no shutdown ... no crash. I also use Win
Pro. Could the problem be OS dependent?



When MSIE6 saw the test image it gave that message and asked for
information, please. Once the information had been transmitted, MSIE
closed.

When Opera6 saw it, it opened and displayed with no comment or problem.

Both in WinXP Home with all patches up to but not including the Massive
Patch 2.

It seems to be totaly browser dependant.
I have IE 4.0 and Mozilla 1.7a on Win98SE.
IE shows an error (with the option of "close" or "details").
Mozilla just shows the pic of the smiling woman with no problems.

Maybe she's just smiling to cover up the fact that she has
problems. :-)

Eh? C is primitive enough that it's effectively shorthand
assembler. It providess almost all of the same flaws as assembler,
certainly. Unix happens to be tied to it becuase it was reimplemented
with C to make for slightly easier porting.

You are, presumably, aware that C was pretty horrible when it arrived,
and that it was itself directly derived from earlier languages?

C++ is (IMHO) the worst thing that ever have happened to
programming. It is a totally horrible thingie. Too big, too
unsecure to be called really Object Oriented, not really all
that compatible with C, no standard for load objects, etc, etc,

unsecure? C++ is a bolted on framework for C that pretends to various
object-oriented things at compile time without once having an actual
object.

Hmmm ... Object Pascal ... As far as I understand Delphi Object
Pascal is a subset of Object Pascal. Don't like the sound of that.

Oh? Can you name a language that allows you to write a non-trivial
program that runs, unchanged, on any platform? I think you'll find
that this isn't really as useful a goal as you seem to think.

Now - one of the most important issues is libraries. You need a good
set of libraries. Another one is support - you don't want to use a
language that don't support the latest things and where compiler

Love it. How doy ou reconcile "language that doesn't support the
latest things" with "runs on every platform" ?

Now - I don't suppose any other language than C++ really supports
the latest direct x and have libraries for XML soap. Hmmm .. Java
might, but that is a toy language IMHO. It does not even have unsigned
integer. Lots of serious programming assumes that.

You have no idea what you're talking about here. Lots of languages
have support for XML SOAP. The point of which is to remove
language-dependence from RPC.

The greatest hoax ever pulled on the programming
community was the introduction of C. I suspect
K & R are still laughing.
